Preparation and Evaluation of Acetabularia-Modified Carbon Paste Electrode in Anodic Stripping Voltammetry of Copper and Lead Ions

Figure 1

One cycle of CV run with a scan rate 100 mV/s with a potential range from −1100 mV (initial) to +1400 mV (final) with positive initial direction for three electrodes: (a) blank electrode; (b) Acetabularia-CPE. The supporting electrolyte is 0.1 M KNO₃.
